Background Introduction
Some old escalators use short pitch roller chain step chains. These
escalators are usually used in commercial and public transport
occasions,like shopping mall, office buildings,
hospitals, exhibition centers, hotels and airports, metro,
etc. Therefore, there are strict requirements on the quality
and safety of step chain as step chain is the
key component in the escalator. After perennial use, if the
step chain has worn out and reached its design service life, it
must be replaced timely and propertly.
Product Detail
step chain pitch P = 67.73mm, 6P = step distance =
406.4mm.
The chain is connected to its left and right side link by
solid axles. This design structure of left, right side
link and solid axles is detachable. Normally, the solid axles are
reserved for use. the single - strip link of step chain
purchasing independently, and it is not include long axles,
which are specified to define escalator width type of 1000,
800 or 600.
The step fixing with step chain is to use clamp bush and
the step chain is used oil for lubrication.

a step distance of 406.4mm. It is suitable for "J" type
escalator, etc.
Producti and Quality Control
The step chain productio by Industry-Renowned step chain suppliers.
The entire step chain manufacture process includes meterial
imgress, component machining, part heat treatment and final
assembly with quality control plan to eansure each step chain
achieved original design requirement. The quality level is
consistent with international first-class brand escalator step
chain.
All type step chain achieved CNAS type test certificate.
Our service
Our professional engineering team can provide technical support to
help clients identify the appropriate step chain specifications to
meet safety and lifetime requirements.
We kindly request our clients to provide us with any documents
related to the escalator chain, e.g. technical service reports,
spare parts numbers of the chain, drawings of the chain, breakage
load certificates/breakage load calculations, etc. These documents
can considerably speed up an inquiry and clarify discrepancies. To
avoid any risk of providing a non-functioning chain, complete this
questionnaire and an identification template with detailed
photographs of the link plates, rollers, step pins, axles, axle
parts and markings on the components. Please fill in the following
points and chain templates as completely as possible. If the
template deviates from the chain to be measured, sketch, measure
and photograph the deviation in detail.
